Description

Attempting to use gdal2tiles to generate tiles.

Unable to exclude the generation of blank tiles, this would normally be done using the --exclude or -x flags

What I Did

            gdal2tiles.generate_tiles(source_path, destination_path,
                                      zoom=[18, 20],
                                      nb_processes=4,
                                      resume=True,
                                      tile_size=256,
                                      srcnodata=0,
                                      verbose=True,
                                      webviewer=all
                                      )

Adding or enabling one of the following would be very helpful

exclude=True
exclude="--exclude"
exclude="-x"
flag="-x"

If I've misunderstood how the exclude works please let me know.
